lied atthe top oil fallingmod 1- llii) lllI) wires, parts adjacent thedrop wires, in addition to the yarns or threads themselves, free andclear from lint.

In the case of this embodiment of the in..

vention, the main support of the blower is a rod or shaft 10 whichextends across the width of the machine, above the top of the latter,said rod or shaft being mounted in place by having its ends fixedlyengaged with stands 111 rising from the tops of the side-frames of themachine. One of said stands is partly broken away in Fig. 2. In thisinstance, the blower is located at midwidth of the series of yarns orthreads, which is an effective position for enabling it to keep theyarns or threads and the desired machine parts clear of lint. It is anelectric fan, which is preferred, although the invention is notnecessarily restricted in all instances to the employment of a fanblower.

To provide for swinging movements transversely of the machine, the fanis mounted between the depending arms of a bail or yoke 12 that hangsdown from the supporting rod or shaft 10, the fan-casing being furnishedwith journals 13, 13, working in bearings in connection with the saidarms. The bail or yoke occupies a vertical plane corresponding ingeneral direction with the length of the yarns or threads, so that thefan swings in a vertical plane at, or substantially at right angles withsaid length.

To provide for the convenient connection of the yoke with the supportingrod or shaft 10, a collar 101 is placed upon said rod or shaft, saidcollar being furnished with a downwardly-extending stud or pin 102, andthe bail or yoke is provided with a hub 121 which fits upon said stud orpin. A clamping screw 122 applied to the said hub serves to hold thebail or yoke in place upon the stud or pin, with capacity for adjustmentup and down to vary the height of the fan above the yarns or threads,etc., and also with capacity for angular adjustment around the stud orpin in case it should be desired to vary the angle which the plane inwhich the fan swings makes relative to the length of the yarns orthreads. The collar 101 is fixedly engaged with supporting rod or shaft10 by means of a clamping screw 100, enabling the collar and fan to beadjusted upon said rod or shaft transversely of the machine, if desired.

According to the present invention, the means actuated from the drivingmechanism of the machine by which the blower is swung to cause thecurrent of air therefrom to sweep back and forth across the width of themachine, comprises in this embodiment a cam in connection with agear-wheel 17 that is in mesh with a pinion 19 on shaft 20 of windingdrum 20, and devices intermediate the said cam and the blower. The camin question is constituted by a camgroove 170 in the gear-wheel 17 andthe main element of said devices is a rocker to which rocking movementis imparted from the cam. In this instance the rocker is a sleeve 14that surrounds rod or shaft 10, it having fixed upon one end thereof bymeans of a clamping screw 160 an arm 16 which is connected by a link 32with an arm 31 projecting from one of the journals 13 of the fan-casing,whereby when the sleeve 14 is rocked around rod or shaft 10 swingingmovement is imparted to the fan-blower. Operative connection between therocker and the cam is established by means of an arm 15 that is fixedlyconnected by a clamping screw 150 with the sleeve 14, a link 30 havingits upper end engaged with the arm 15, and a lever 28 pivoted at 29 uponthe machine-framing, provided with a camfollower 27 working incam-groove 170, and having the lower end of link 30 connected with it. v

The fan 11 is shown provided with a guard 21 of usual character aboutits blades. In practice, suitable lead-wires m, Fig. 3, are connectedwith the fan. In Fig. 3 these lead-wires are merely indicateddiagrammatically, to enable their general course to be traced. Asuitable switch is provided for controlling the actuation of the fan. Inthis instance, such switch is indicated at 22, Fig. 3, located at thebottom of one end of the machine. The plunger 220 thereof is arranged tobe depressed by a finger 23 upon the pedal-rockshaft 24, so as to closethe switch and let the current flow only when the warping machine isrunning on high speed. With the switch arranged to be actuated from thepedal-rockshaft as just described, the blower is automatically set inaction and commences to oscillate as soon as the warping machine is puton high speed. By reason of having the axis of oscillation disposedlengthwise of the Inachine, so that the plane of oscillation istransverse, i. e., widthwise of the machine, at right angles to thedirection of the length of the yarns or threads, or substantially so,the blast of air is swept back and forth to clear the yarns, combs,drop-wires, etc., throughout the entire width of the machine. Theefi'ect of the blast or current as it acts upon the yarns, etc., issubstantially uniform across the entire width of the machine.

In some instances, we contemplate substituting a nozzle for deliveringair under moderate pressure in place of the electric fan which isillustrated in the drawings. We claim as our invention: 1. I11 a warpingmachine or the like, in combination, a supporting shaft, a blowermounted upon said shaft with capacity for swinging movement transverselyof the machine, and means for swinging the blower to cause its blast tosweep across the width of the series of yarns or threads, comprising asleeve upon the said shaft provided with arms, a cam, a cam-actuatedmember operatively connected with one of the sleeve-arms, and operativeconnections between a second sleeve-arm and the blower, to rock thelatter when the sleeve is rocked.

2. In a warping machine or the like, a lint-clearer comprising a blowermounted for swinging movement transversely of the machine, an actuatingcam, and arocker actuated by said cam and connected with the blower forswinging the blower to cause its blast to sweep across the width of theseries of yarns or threads.

3. In a warping machine or the like, a lintclearer comprising a blowerlocated at a fixed point in the width of the machine, and means actuatedfrom the driving mechanism of the machine for swinging the blower tocause the current of air therefrom to sweep back and forth transverselyacross the width of the machine.

4. In a warping machine or the like, a lint-clearer comprising a blower,a yoke or supporting frame to which the blower is connected withcapacity to rock or swing,

an overhead support for said yoke or supporting frame located at a fixedpoint in the width of the machine, and means for adjusting the yoke orsupporting frame vertically upon the said overhead support.

5. In a warping machine or the like, a lint-clearer comprising a blower,a yoke or supporting frame to which the blower is connected withcapacity to rock or swing, an overhead support for said yoke orsupporting frame located at a fixed point in the width of the machine,and means for adjusting the yoke or supporting frame angularly in ahorizontal plane upon the overhead support.

6. In a warping machine or the like, a lint-- clearer comprising ablower, in combination with a yoke or supporting frame to wh ch theblower is connected with capacity to rock or swing, and an overheadsupport for said yoke or supporting frame located at a fixed point inthe width of the machine, one of the latter elements having a pin orprojection and the other a sleeve adjustably fitting upon said pin orprojection, and

means for fastening said sleeve and said pin or projection together.
